The identity of Orius tantillus (Motschulsky) and notes on other Oriental Anthocoridae (Hemiptera,Heteroptera)

Abstract

Studies on the biology of Toxoptera aurantii (Boy.) showed that populations of the aphid contain females only, and that reproduction is parthenogenetic and viviparous and occurs exclusively on the undersurface of flush leaves. The aphid is described and a key is drawn for the various instars. The development of the aphid is temperature-dependent but at the optimum temperature it takes 6 days to become adult. The incidence of alates in populations is influenced both by high aphid density and leaf age.
